To @ZZ whom t mctyooncern:

Be itknown that I, Nrcnonns BOREN, a citiz'en ofthe United States,residingatPrinceton, in the county of Gibson and State of Indiana, have invented a new and useful Chu rn, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction of churns and to provide a simple, inexpensive, and efficient one adapted to be easily operated and capable of rapidly effecting the production of butter.

The invention consists in the construction and novel combination vand arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a churn constructed in accordance with this invention. Fig. 2 is an enlarged detail sectional view illustrating' the manner of connecting the pumpspand the dasher to the reciprocating slider Fig. 3 is a detail view of the dasher. l

Lilie numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a supporting-frame composed of longitudinal top bars 2 and 3 and supporting-legs 4 and 5, arranged in pairs at the ends of the frame and suitably secured to the longitudinal top bars, which are connected at their ends by cross-bars 6 and 7. The crossbars 6 and 7, which are disposed horizontally, extend across the space between the top bars and have their ends secured in suitable openings or mortises of the latter. The legs 4f and are inclined and converge toward the top of the frame, and the legsei are extended above the top bars 2 and 3 and are provided with suitable bearings for a transverse shaft 8 and are supported by inclined braces 9, extending upward from the top bars, ata point between theendsthereof,andsuitablyconnected with the extensions of the legs. 4t. The transverse shaft has mounted upon it a pulley lO, arranged between the upper ends of the extensions of the legslc and located above the intermediate space between the top bars of the frame and connected by a belt 11 with a drivcwheel12. The drive-wheel 12,\vhich is arranged between the top side bars of the frame, is mounted on a short transverse shaft 13, journaled in suitable bearings 14 and having a crank-handle 15 secured to one end of it by means of whichit is operated. The upper transverse shaft 8 also carries a wheel 16, `which is weighted at one side to form a tly or balance wheeland which is provided at the opposite side with a wrist-pin 17, by means of which it is connected with the upper end of a pitman 1S. The pitman 1S extends downward from the wheel 16 and is connected at its lower end by a suitable pivot 19 with a verticallyreciprocating slide 20. The vertically-reciprocating slide, which consists of a block, is provided with a dovetailed groove 21, located at its inner face and receiving a dovetailed flange or rib 22 of a vertical guide 23 mounted on the frame and secured tothe outer face of the top bar 2. l/Vhen the gearing is operated by rotating the crank-handle, the slide 19 is reciprocated, and it carries with it a dasher-rod 24C, connected with the slide by a suitable fastening device and adapted to be readily detached therefrom. The dasher-rod, which passes through a central opening of a cover 25 of a churn-body 26, is provided at its lower end with a suitable dasher 27 for actuating t-he contents'ot' the churn-body. Any suit-able form of dasher may be employed, and in order to facilitate and increase the production of butter a pair of pumps 27 is provided.l bThese pumps 27', which are adapted to force air through the contents of the churn-body, are constructed similar to an ordinary bicycle-pump, and they consist of invertedcylinders secured at their upper ends to a cross-bar 28 and hollow stems or tubes 29, mounted on the cover and extending downward therefrom to within a short distance of the bottom of the body. The hollow pistons or tubes 29 are provided at their upper ends with suitable piston-heads, and they have attachment-plates 3l fixed to them at .points between their ends. The attachment-plates, which are preferably concavo-convex, as illustrated in Fig. 2 of theV accompanying drawings, rnay be of any other desired shape, and they are secured to the lower face of the cover of the churn-body by suitable fastening devices. The pump-cylinders are provided at their lower ends with removable sections or IOO caps 32, adapted to be detached to permit the cover to be removed from the churn-body. The lower sections or caps are preferably screw-threaded, and when separated will enable the cover to be removed from the churnbod y, the dasher being detachably secured to the slide, and the central opening of the cover being of sufiicient size to permit the head or upper end of the dasher-rod to pass through it. When the slide is reciprocated vby the gearing, it reciprocates the vertically-movable dasher, and it carries with it the cylinders of the air-pumps, so that while the contents of the churn-body are agitated air will be forced through the cream, and butter will be rapidly produced.

It will be seen that the churn is exceedinglysimple and inexpensive in construction, that it is easily operated, and that it is capable of thoroughly and rapidly agitating the cream and of simultaneously forcing air through the same, whereby butter is rapidly produced.

The air-pumps, Which may be constructed in any suitable manner, are provided at their piston-heads with suitable valvesof the ordinary construction for preventing the liquid contents of the churn-body from being drawn into the tubular stems at the backward or upward stroke of the cylinders.

What I claim is- 1. In a churn, the combination of a frame having a vertical guide, a slide mounted on the guide, a dasher-rod connected with and carried bythe slide, a churn-body, and an air-pump composed of an inverted cylinder carried by the slide, and a tubular piston fixed to the churn-body and extending into the same and provided with a piston-head arranged Within the cylinder, substantially as described.

2. In a churn, the combination of a frame provided with a guide, a reciprocating slide mounted on the guide, a churn-body, a dasher operating in the churn-body and connected with the slide, a pair of air-pumps located at opposite sides of the dasher-rod and composed of inverted cylinders carried by the slide, and tubular pistons fixed to the cover of the churnbody and extending into the latter and provided with piston-heads arranged within the inverted cylinders, and gearing for recipro cating the slide, substantially as described.

3. In a churn, the combination of a frame provided with a vertical guide, a slide mounted on'the vertical guide, a ily-wheel located above the slide, a pitman connecting the ily-V wheel and the slide, gearing for rotating the ily-wheel, a churnbody, a dasher having a rod connected with the slide, and the airfpumps composed of inverted cylinders carried by the slide, and the tubular piston-rods provided at their upper ends with piston-heads and having attachment-plates 4arranged between the ends of the tubular pistons and fixed to the cover of the churn-body, substantially as described.

4. In a churn, the combination of a frame, a vertical guide mounted on the frame and .provided with a dovetailed rib or flange, a

slide having a dovetailed groove to receive the rib or flange and provided with a crosspiece, a dasher-rod secured to the slide, pumpcylinders mounted on and depending from the cross-piece, the stationary tubes forming pistons and provided at their upper ends with piston-heads arranged within the cylinders, and means for reciprocating the slide,.sub stantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
